    High powered aftermarket stereo systems draw a lot of power, and if your electrical system isn’t upgraded you can have poor audio performance no matter how great the amplifier or subwoofers. Plus you can have more serious problems like dimming headlights or a vehicle that won’t start. We have the products you need to power your system including power cells, capacitors, inverters, converters, and power supplies.

    If your headlights are dimming when the stereo is cranked up, you’re drawing too much power and straining your electrical system. The first step is to check the entire electrical system for soundness including grounds and alternator output, but one way you can upgrade your system is with a power cell type battery. These are AGM (Absorbed Glass Mat) type batteries, where the battery electrolyte is absorbed in glass matting that is akin to a sponge.

    AGM batteries are completely sealed, spill proof, and maintenance-free, and can be mounted in any position. But the most important feature is their low resistance and greater plate area, which provides more power for your system. These batteries are a great choice if you’re adding a second battery to your system, especially if you play the stereo for long periods with the engine off. Another addition you can make to your system is a capacitor. A capacitor stores power and can deliver it more quickly than a battery, such as when bass notes or drum beats put large power demands on the amplifier.

    Another option for powering your system with the engine off is a power converter or power supply. These units convert house current into 12 volts DC, so they can provide power to your stereo and any other 12V DC components. They’re available in a wide range of power ratings and many include a microprocessor controlled battery charger that continuously monitors battery state of charge and load and charges the battery accordingly. Units with a battery charger are designed to be mounted in the vehicle and always connected to the battery.

    Works Great
    Arrived on time. I'm able to plug in my house vacuum to clean inside my truck. No more super long extension cords. (I live in a apartment complex).
